[webkit-dev] licensing questions

[Jakob Praher]

hi people,

i am very excited about the webkit project. i think some of its core 
libraries are quite interesting outside of webkit/webcore. especially 
the text and encoding part is interesting to me.

but i have to say that i am a little bit confused by the different 
licenses:

for instance:

WebCore/platform/text/StringHash.h is under GPL2+ whereas 
/WebCore/platform/text/TextCodecICU.h has a BSDish license.

Is this mix of licenses needed?
Is it possible to link a non-free-software application against e.g. 
WebCore without getting into troubles?

thanks in advance
